  Verfahren zur Reinigung von Arsenchlorverbindungen und andere Verunreinigungen in dampfförmigem Zustande enthaltenden Gasen. 



   Durch das deutsche Patent Nr. 179513 ist ein Verfahren zur Reinigung von Arsenchlorverbindungen und andere Verunreinigungen in dampfförmigem Zustande enthaltenden Gasen, insbesondere von aus den Sulfatöfen kommenden Salzsäuregasen bekannt geworden. 



   Bei Ausführung dieses Verfahrens hat sich nun ergeben, dass die zum Reinigen be-   nutzten   Mineralöle sich während des Betriebes in kurzer Zeit nach der Richtung hin ver- ändern, dass Chlor in die Kohlenwasserstoffe eintritt. Die Folge davon ist, dass die Öle ihre reinigende Eigenschaft verlieren und auch spezifisch schwerer als Wasser werden. Die weitere Folge ist, dass man erhebliche Mengen 01 für die Reinigung einer bestimmten Menge Gas verwenden muss. 



   Die vorliegende Erfindung hat den Zweck, diesen   Übelstand   zu beseitigen. Sie beruht auf der Beobachtung, dass jene schnelle Veränderung der reinigenden Öle auf die verhältnismässig hohe Temperatur zurückzuführen ist, unter der die Gase den Sulfatofen verlassen und mit dem Öl zusammentreffen und dass diese Veränderung auf ein um so geringeres Mass   zurückgeführt   wird, je weiter man die Gase abkühlt. Man verfährt also nach dem vorliegenden Verfahren in der Weise, dass man die Gase, nachdem sie den Sulfatofen verlassen haben und bevor sie mit dem reinigenden 01 in Berührung kommen, abkühlt.

   Beim Abkühlen auf   gewöhnliche   Temperatur wird die besagte Veränderung des reinigenden Öles so herabgesetzt, dass sie betrieblich nicht mehr in Betracht kommt und infolge des dadurch bedingten geringen Verbrauchs an Mineralöl ein betrieblich und wirtschaftlich gutes Resultat ergibt.

  Process for the purification of gases containing arsenic chlorine compounds and other impurities in a vaporous state.



   The German patent no. 179513 discloses a process for the purification of arsenic chlorine compounds and other gases containing impurities in a vaporous state, in particular hydrochloric acid gases coming from the sulfate ovens.



   When carrying out this process, it has now emerged that the mineral oils used for cleaning change within a short time during operation in the direction that chlorine enters the hydrocarbons. The consequence of this is that the oils lose their cleaning properties and also become specifically heavier than water. The further consequence is that one has to use considerable amounts of 01 for cleaning a certain amount of gas.



   The present invention aims to remedy this drawback. It is based on the observation that the rapid change in the cleansing oils is due to the relatively high temperature at which the gases leave the sulphate furnace and meet the oil and that this change is reduced to a lesser degree the further you go Gases cools. According to the present method, one proceeds in such a way that the gases are cooled after they have left the sulphate furnace and before they come into contact with the cleaning oil.

   When cooling down to the usual temperature, the said change in the cleaning oil is reduced so that it is no longer operationally relevant and, due to the low consumption of mineral oil that this causes, produces an operationally and economically good result.
